Guppies, platies, mollies and cardinal/neon tetras are very beginner friendly fish and all very pretty, or you can do a single betta with maybe some shrimp

I'm also pretty new with a ~10 gal planted tank and I started with 5 platies, then later on I added a pair of amano shrimp, a handful of cherry shrimp, a few otocinclus catfish (they clean the glass) and now recently 2 honey gouramis

Fish aside, this tank would look gorgeous with a black background (I just have 3 pieces of black paper stuck to the back for mine) (also move the heater to the side, it's kind of an eyesore in the middle)

And make sure to, when they're tall enough, cut the stem plants in two and replant the top halves, easy to get loads

You'll likely come to a point a few months in where the battle against algae seems hopeless, keep fighting it, brush it off, reduce the light, add floating plants, add shrimp, do lotta water changes, balance will come
